A 500°F (260°C) top-loading, electrically heated oven is used for heat treating parts.

In a typical multi-burner furnace with numerous temperature measurement points, the change in a single burner’s firing rate can alter the thermal profile inside the furnace in a nonlinear fashion. Consequently, each independent tuning adjustment has cascading downstream effects on the rest of the system.

Sheffield Forgemasters announced a breakthrough in the industrialization of electron-beam welding (EBW) for thick-section materials. Using EBW, the company weld-joined two 200-mm-thick (8-inch-thick), 3-meter-diameter (9-foot-diameter) forged vessel sections of nuclear-grade steel. The weld, equivalent to approximately 10 meters (32 feet) in length, was completed in a single pass and in a dramatically short timeframe. The weld was completed in 140 minutes with no reportable defects shown in preliminary nondestructive testing (NDT). A weld of this kind would typically take months and include numerous stages of NDT and heat treatment.

American Axle & Manufacturing (AAM) secured multiple next-generation full-size truck front and rear axle programs with global OEM customers. These contracts, including a previously announced award in early 2021, are expected to generate more than $10 billion of lifetime revenues from mid-decade to beyond 2030. 

ArcelorMittal confirmed with the government of Ontario its plan for a $1.4 billion investment in decarbonization technologies at ArcelorMittal Dofasco’s plant in Hamilton. The investment will reduce annual CO₂ emissions at the facility by approximately 3 million metric tons, which represents approximately 60% of emissions. This means the Hamilton plant will transition away from the blast furnace/basic oxygen furnace (BOF) steelmaking production route to the direct reduced iron (DRI)/electric-arc furnace (EAF) production route. The project is scheduled to be complete by 2028.

United States Steel Corp. broke ground in Osceola, Ark., on the company’s next-generation highly sustainable and technologically advanced steel mill. According to U.S. Steel, the $3 billion steelmaking facility will be the most advanced in North America and largest private project in the history of Arkansas. The plant will be adjacent to U. S. Steel’s Big River Steel, and the two facilities will be known as Big River Steel Works. The facility is expected to bring 900 plant jobs to the area, along with thousands of construction jobs. It will include two electric-arc furnaces (EAFs) with 3 million tons per year of advanced steelmaking capability, an endless casting and rolling line and advanced finishing capabilities.

It is not news that automotive industry is trying to reduce the overall weight of its final products – vehicles. One commonly accepted way to achieve this goal is to look into material weight reduction. In other words, build parts as strong as normal but with lighter materials.

United States Steel and Carnegie Foundry, a robotics and AI studio, jointly announced a strategic investment and partnership. The two Pittsburgh-based companies will work to accelerate and scale industrial automation driven by advanced robotics and artificial intelligence (AI). Carnegie Foundry will use this investment to commercialize and scale its industrial automation portfolio of robotics and AI technologies in advanced manufacturing, industrial robotics, integrated systems, autonomous mobility, voice analytics and more.
